SUN RPC NUMBERS To obtain SUN Remote Procedure Call (RPC) numbers send an e-mail request to "rpc@sun.com". The RPC port management service ('portmap' in SunOS versions less than 5.0 and 'rpcbind' in SunOS versions greater than 5.0) "registers" the IP port number that is allocated to a particular service when that service is created. It does not allocate ports on behalf of those services. For an exact specification of the semantics refer to the source code of svcudp_create() and svctcp_create() in the archives. In short however is that these interfaces, and svc_tli_create their Transport Independent RPC equivalent, take either a user specified port number or RPC_ANY (-1) which effectively means "I don't care." In the "I don't care" case the create code simply calls socket(2) or t_open(3n) which allocates an IP port based on the rules: if euid of the requesting process is 0 (i.e., root) allocate the next available port number in the reserved port range. else allocate the next available port in the non-reserved range. Port numbers count up sequentially. Can a port that is "assigned" can be used when the assignee's service is not present Say port 501 is assigned to the "jeans" service. On a machine that does not have the "jeans" service, nor has any clients that might be expecting to use it, is port 501 available for other uses Any dynamic allocation process, like the portmapper, that chooses the next unused port might allocate port 501 dynamically to a process that asked for a "I don't care" port. So any dynamic allocation scheme may pick an unused port that happened to correspond to a port number that had been "assigned" but was currently unused. While it might be desirable, it is impossible to guarantee that any unused port, even though officially assigned to a service, is not picked by a dynamic allocator since such an assignment might occur long after the delivery of the system into a site that doesn't watch for the latest list. There is the restriction that only "superuser" on BSD derived systems such as SunOS can bind to a port number that is less than 1024. So programs have used this information in the past to identify whether or
